I will start by saying hello to all. First post long time lurker. I am normally on the AR_15 boards.
Yesterday i was shooting with a bunch of co-workers at the range. I had fired about 30 rounds through my glock. I loaded a new magazine, put it in the gun and chambered a round. I fired off about 4 shots. I pulled the trigger again and nothing. I looked at the gun and it appeared there was a failure to extract or a missfeed (would have been the first time in a 1500 rounds to so). I pulled the slide back and what i saw shocked me. http://www.pyrouniverse.com/gallery2/data/861/Stuck_1.jpg Dont mind the casing all bent up that was from me trying to pull it with a pair of angled needle nosed pliers. What i originally saw was a perfect shear. I thought the round fired and some how swole in the chamber then the extractor ripped the back off completely. After getting home and trying to field strip the gun what i saw was a bigger shock. http://www.pyrouniverse.com/gallery2/data/861/Stuck_2.jpg First thoughts were how in the hell did that happen! I have no idea how this happened. I first thought maybe when the casing went to extract it some how flipped around and the slide pushed the casing back into the chamber. But then how could the back of the casing possibly fit into the chamber. Then the idea of a damaged glock started racing through my mind. The only think i could think of it that i wasnt paying attention when loading my magazine i picked up and empty case and put it into my magazine backwards. The put some good rounds on top. When i fired the last "good " round it pulled it and loaded the empy casing backward jamming it in the chamber. To get the casing out i got a wooded dowel rod a little smaller than the barrels bore. I then took some compressed air in a can. I turned the can upside down and "Froze" the bullet casing. Since it was in the barrel backwards the casing was the only thing getting the cold blast. I then put in the dowel rod from the end of the barrel and gave it a few good taps and the casing came out. After stripping the gun down i looked at it and saw that you can infact put a round in the champer backwards. http://www.pyrouniverse.com/gallery2/data/861/Stuck_3.jpg The round actually rests on a shoulder down in the barrel. not on the rim of the casing. http://www.pyrouniverse.com/gallery2/data/861/Stuck_4.JPG All is well and nothing was damaged..... I guess i will pay better attention next time. |

Well, you just learned the difference between rimmed and rimless ammunition.
Rimmed cases work in revolvers where the rim is what "headspaces" the cartridge. Rimless cases work in autos, where the cartridge headspaces off the case mouth. Just ignore the .22, it's the exception that makes the rule :) And I'd say it's more likely that the empty did a 180 on ejection that you loading an empty, backwards, into the magazine. Perfection!

I was originally thinking that too but normally the glocks throw the casings so far i didnt see how this could be possible. |
